A Quote by Pierre-Simon Laplace
The simplicity of nature is not to be measured by that of our conceptions. Infinitely varied in its effects, nature is simple only in its causes, and its economy consists in producing a great number of phenomena, often very complicated, by means of a small number of general laws.

All the effects of Nature are only the mathematical consequences of a small number of immutable laws.
The history of atomism is one of reductionism – the effort to reduce all the operations of nature to a small number of laws governing a small number of primordial objects.
First, it is necessary to study the facts, to multiply the number of observations, and then later to search for formulas that connect them so as thus to discern the particular laws governing a certain class of phenomena. In general, it is not until after these particular laws have been established that one can expect to discover and articulate the more general laws that complete theories by bringing a multitude of apparently very diverse phenomena together under a single governing principle.
Man is made for science; he reasons from effects to causes, and from causes to effects; but he does not always reason without error. In reasoning, therefore, from appearances which are particular, care must be taken how we generalize; we should be cautious not to attribute to nature, laws which may perhaps be only of our own invention.
In general, the more one augments the number of divisions of the productions of nature, the more one approaches the truth, since in nature only individuals exist, while genera, orders, and classes only exist in our imagination.
The true essence of Chinese culture is sophistication, refinement, the spirit of poetry. The spirit of ink painting and calligraphy lives on forever. Calligraphy is more important than painting. Chinese always consider nature. Man is a very small part of nature. That's why in Chinese painting you see huge mountains and man very small, very humble before nature. You must be harmonious and one with nature. You don't fight it. And then there's a bit of a poetry. Of course, it's very complicated, but also very simple.
Others make a point of trying to attain the precision and poise they see in those who have the ability to choose from a great number of horses those with [...] qualities found in only a very small number of horses. This leads to a circumstance in which these imitators of such studied poise mortify the spirit of a noble horse, and remove from it all of the goodness of temperament Nature has given it.
But it is just this characteristic of simplicity in the laws of nature hitherto discovered which it would be fallacious to generalize, for it is obvious that simplicity has been a part cause of their discovery, and can, therefore, give no ground for the supposition that other undiscovered laws are equally simple.
Of the laws of nature, on which the condition of man depends, that which is attended with the greatest number of consequences, is the necessity of labor for obtaining the means of subsistence, as well as the means of the greatest part of our pleasure.
The task of evolutionary psychology is not to weigh in on human nature, a task better left to others. It is to add the satisfying kind of insight that only science can provide: to connect what we know about human nature with the rest of our knowledge of how the world works, and to explain the largest number of facts with the smallest number of assumptions.
[All phenomena] are equally susceptible of being calculated, and all that is necessary, to reduce the whole of nature to laws similar to those which Newton discovered with the aid of the calculus, is to have a sufficient number of observations and a mathematics that is complex enough.
I know that certain minds would regard as audacious the idea of relating the laws which preside over the play of our organs to those laws which govern inanimate bodies; but, although novel, this truth is none the less incontestable. To hold that the phenomena of life are entirely distinct from the general phenomena of nature is to commit a grave error, it is to oppose the continued progress of science.
What we observe is not nature itself but nature exposed to our method of questioning. Our scientific work in physics consists in asking questions about nature in the language that we possess and trying to get an answer from experiment by the means that are at our disposal.
It is thus that the generality of mankind, whose lot is ignorance, attributes to the Divinity, not only the unusual effects which strike them, but moreover the most simple events, of which the causes are the most simple to understand by whomever is able to study them. In a word, man has always respected unknown causes, surprising effects that his ignorance kept him from unraveling. It was on this debris of nature that man raised the imaginary colossus of the Divinity.
We could live at the present day without a Plato, but a double number of Newtons is required to discover the secrets of nature, and to bring life into harmony with the laws of nature.
Thus at every step we are reminded that we by no means rule over nature like a conqueror over a foreign people, like someone standing outside nature - but that we, with flesh, blood and brain, belong to nature, and exist in its midst, and that all our mastery of it consists in the fact that we have the advantage over all other creatures of being able to learn its laws and apply them correctly.
